2018 LU2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 LU2 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2018 LU2 orbits the sun every 489 days (1.34 years), coming as close as 0.82 AU and reaching as far as 1.61 AU from the sun. Based on its brightness and the way it reflects light, 2018 LU2 is probably between 0.008 to 0.034 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2018 LU2's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2018 LU2 has 8 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| June 9, 2022 | 5,662,218 | 10.728 |

2018 LU2's orbit is determined by observations dating back to June 7, 2018. It was last officially observed on June 22, 2018. The IAU Minor Planet Center records 42 observations used to determine its orbit.
2018 LU2 can be reached with a journey of 386 days. This trajectory would require a delta-v of 11.666 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 14 potential trajectories and launch windows to this asteroid.
